I actually now use the SU model to start my autocad drawings... I model in real sized, and thicknesses of walls and such. if you download my template from the "How A Pro Builds a House in SU" tutorials in the Tut section. you'll see I have about 10 scenes that I use to export DWGs elevation Front, Rear, Left, Right, Section North to SOuth, East to West, Floor Plan I, Floor Plan II, Floor Plan III... then I take those plain dwgs and start dimensioning and noting them.
I also use them to Wow clients and allow them to live in the house for a few days before moving on to the next phase. Sketch to SU Prelim, SU Prelim to Construction Docs.
I have not built as the "builder" anything residential... that is my ultimate goal, to build mine and my mothers designs
I have been the project manager of several commercial projects Bass Pro in Las Vegas is one of them, Bass Pro in Myrtle Beach SC is another, a few popular stores in malls across the USA, Addias, Tommy, Chica Fila... etc.
and a carpenter on quite a few residences in my earlier career.
I'm very pleased that you enjoy them... some clients tend to dumby them down, and square them up... which is the point I normally tell them to take a leap... lol
